Abstract

The representative Limit State Design(LSD) codes, AASHTO LRFD and Eurocodes, are widely being applied when designing civil structures. However, these codes are only applying tunnel lining design and segments design for shield tunnels. Recently in Europe, the Eurocode 7 committee was trying to create a research group called EG12, but they reluctantly decided not to create EG12 since it could have an impact on some of the other Eurocodes(including Eerocodes 2 and 3). Still there is an effort to continue researching LSD for tunnelling. LSD method will become the norm for the field of civil structural design in the near future. Therefore, it is important to fully understand Eurocode7:Geotechnical design in connection with Eurocode 2 and Eurocode 3. In addition, it is essential to follow international research trends and also to research for application to tunnelling.

대표적인 한계상태설계법은 AASHTO LRFD와 Eurocodes가 있으며, 토목구조물 설계에 폭넓게 적용되고 있다. 그러나 이러한 설계법이 터널설계에 적용될 경우에는 NATM 터널의 라이닝설계와 쉴드터널의 세그먼트 설계에만 제한적으로 적용되고 있다. 최근 유럽에서는 유로코드를 터널설계 전분야에 적용하기 위하여 기준개정(EG12)을 추진하였으나 다른 유로코드(EC2 및 EC3)에 미치는 영향 등을 고려하여 불가피하게 구성하지 않는 것으로 결정되었다. 그러나 여전히 한계상태설계법을 터널설계에 적용하기 위한 연구를 활발히 진행하고 있다. 한계상태설계법은 가까운 장래에 터널을 포함한 토목구조물 설계법의 주류가 될 것이다. 그러므로 Eurocode 7 등 국외 한계상태설계법에 대한 충분한 이해가 중요하며, 국제적인 연구동향을 파악하고 터널설계에 적용하기 위한 연구가 필요하다.
